This 4.23ct lab-grown asscher sits in the three to five carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG830661925 or 830661925. Listed at 23 retailers as of October 29, 2026, with prices from $1,382 to $9,819, a $8,437 spread on the same certified stone. Blue Nile lists it at $9,819. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
